Gestalt, Navon and Kanizsa illusion processing in CVI, ADHD, and dyslexia Children with Normal verbal IQ.

Introduction: Global Visual Selective Attention (VSA) is the ability to integrate multiple visual elements of a scene to achieve visual overview. This is essential for navigating crowded environments and recognizing objects or faces. Clinical pediatric research on global VSA deficits primarily focuses on autism spectrum disorder (ASD).

Developmental trajectories of visual orienting functions in children born very or extremely preterm.

Background And Aims: Preterm birth increases the risk of neurodevelopmental impairments, such as Cerebral Visual Impairment (CVI), which affects visual processing. Assessing visual functions in young children is challenging with traditional methods that often rely on verbal/motor responses. The aim of the study was to investigate the developmental trajectories of Visual Orienting Functions (VOF) in children born very preterm (<32 weeks gestational age) between 2 and 5 years corrected age (CA) using eye tracking.

Characterization of Gaze Metrics and Visual Search Pattern Among Glaucoma Patients While Viewing Real-World Images.

Prcis: We quantified and compared the gaze metrics during target-oriented visual search tasks between glaucoma and healthy controls. On the basis of a mathematical concept we showed that due to glaucoma, focal search becomes prominent over global search.

Purpose: Visual search (VS) which is essential for target identification and navigation is significantly impacted by glaucoma.

Eyes on CVI: Eye movements unveil distinct visual search patterns in Cerebral Visual Impairment compared to ADHD, dyslexia, and neurotypical children.

Visual search problems are often reported in children with Cerebral Visual Impairment (CVI). To tackle the clinical challenge of objectively differentiating CVI from other neurodevelopmental disorders, we developed a novel test battery. Visual search tasks were coupled with verbal and gaze-based measurements.
